The distribution of fragments resulting from collisions between 50--200-keV C{sub 60}{sup +} ions and H{sub 2} and He is found to follow approximately a simple power law {ital I}({ital m})={ital cp}{sup {ital m}} where {ital p} is a constant depending on both energy and target gas, and {ital m} is the number of missing pairs'' of carbon atoms. Based on this observation, a new dynamical fragmentation model involving the ratio of two characteristic times is proposed. In collisions by 300-keV C{sub 60}{sup ++} ions, the singly charged products are distributed quite differently, which implies the first evidence of the presence of charge-separation reactions.
